There is no strategy in a game of chances, I mean you are placing your faith on a ball and a spinning roulette and wishing that it will land at the right spot but at the same time at the back of your mind you know that there isn't such thing. And yes, the only strategy that exist in this kinds of games is based on your bankrolls and how to make your money last a long time. Only strategy that I think can help in a way to win a roulette is to list 1000 spins and their results and get their average and bet on those number in between but that too is unreliable and tiresome to do.
It isn't actually unreliable tbh, but rather the concept of randomness just defeats the numbers that result in the average you would get. Just like my point earlier, a person could perfectly get a split 50/50 rewards/loss in 100 spins, but it could also happen that a person could get 100 losses in 100 spins. Tiresome though? That I agree 100%. Not to mention that it'd be a fruitless endeavour since even if you knew the numbers, you'd still have the chances of winning/losing.
Honestly, this game is not something that will give gamblers a good chance of winning.
Yes, there are winners but they need to be extremely lucky to win big time, and OP's strategy will not work, I'm confident with that.
No way to win in a game with a huge house edge, the house always wins as they say and that's the reality.
The game maybe fun but the chance of winning is low.
I don't think that you need to be very lucky to win with roulette, everyone can do it. The game is standardised all around the world, everybody knows chances of winning beforehand. Sure there is a house edge in place, but it's small compared to other games. When betting on Red/black or Odd/Even we are getting very close to a coin flip. And no one would over you a chance to double your money without some payoffs. I think 50/50 odds are pretty good to work with if you follow a strategy.
I think what he wanted to point out was compared to other gambling games, roulettes are just on the worse side of things. It'd be a lot better to do other games such as poker or blackjack maybe, though that's just imo.
